Getting to Know CHALLENGER 4T-AT 10W-40: What is it? And Why is it Important?
H2: Getting to Know CHALLENGER 4T-AT 10W-40: What is it? And Why is it Important?
For those who have just started maintaining their motorcycle themselves, you might have noticed the numbers on the oil gallon labels and felt a bit curious. If you are asking, "What is 10W-40 motorcycle oil?", let us explain it simply. These numbers and letters are codes representing the "Viscosity Grade," which is an international standard used to determine the thickness and flow of the engine oil.
-
10W: The number 10 followed by the letter "W" (which stands for Winter) indicates the engine oil's viscosity grade under low-temperature conditions.
-
40: The number 40 at the end represents the oil viscosity grade while the engine is operating at high temperatures. Selecting the appropriate viscosity depends on the specific requirements of each engine type and its intended application.
Basic Inspection Guide for "Nong Kram" Before Your Next Oil Change
Before choosing your next engine oil, it is essential to regularly observe and check the condition of your favorite motorcycle. Monitoring these signs will help you identify the right time for maintenance before cumulative engine damage occurs. Here are the primary warning signs you can check by yourself.
-
Reduced Acceleration and Lack of Power : If you feel your bike is becoming "sluggish" or the throttle response isn't as punchy as it used to be, it could be due to several factors. Often, it's caused by old engine oil that has become thick and accumulated dirt over time, causing the engine to struggle. Alternatively, it might be the result of using an inappropriate viscosity grade for your specific engine.
-
Oil Color and Level: You can manually check the oil level using the dipstick while also observing its appearance. If the oil has become significantly thicker, looks cloudy, or appears contaminated, it is highly recommended to have a professional technician inspect your engine.
